RegistryFusion™ installable Whois software

NOTE

These products have been discontinued. This page is just for historical reference.

The RegistryFusion system offers a choice of three interfaces that you can install on your own Windows machines. Because they operate from your IP addresses, queries you make with these tools will be subject to the usual query limits imposed by Whois server operators.

HexWhois™ .NET Class Library

The class library offers maximum control of queries and returned data. You can use it from both .NET applications and COM clients.

Whois XML Proxy Server

The XML Proxy Server runs as a Windows Service (no IIS needed) and listens on port 43, just as a regular Whois server does. It takes a simple string of input and returns the same XML as the web service.

Special features of the installable proxy server:

Provides a means of limiting quantity and rate of usage by IP address on a local network

Can cache XML results in a SQL Server database to avoid the cost of duplicate queries

Microsoft .NET Framework 2.0 SP1, 3.0 SP1, 3.5 SP1, or later. (To see if you already have it, look for “Microsoft .NET Framework” under Control Panel -> Add/Remove Programs.) You can get it through Windows Update.
